MY printer is an HP 810c and tests in troubleshooter as OK.
My Laptop is a Dell 620 fully updated system wise and Libre Office.
I have 2 Gig RAM so plenty of storge. Running 2.0 dual core.
Problem: Randomly... not EVERY document. May be two pages or 30 pages, the printer stops printing mid-page, whole system including laptop locks up requiring holding down power key to shut off and reboot.
Upon reboot, immediately printer spits out unfinished page, usually prints page of garbage, and starts printing doc from beginning. If I shut off printer, cancel doc in que, sometimes printer still wants to print entire doccument, sometimes I can click to print missing pages in LibreOffice.
I don't know if hang up is caused by printer or something in laptop.
